IMPROVEMENT IN OPERATING DAIvIPERs IN s'rov'Es.

Specification forming part of Letters Patent No. 34,446, dated February 18, 1362.

To all whom it may concern.-

Be it known that I, OsoAr. PADDocK, of .Vateitown, in the county of vJefferson and State of New York, have invented a new and useful Improvement in Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a vertical longitudinal section taken centrally through the stove or furnace and flues, exhibiting my improved arrangement of valves and connecting-rods, showing the same in two positions. Fig. 2 is a view looking in the rear of the stove, showing the inclined and horizontal flues, also the main chimney-flue.

Similar letters refer to like parts in both figures.

This invention is an .improvement on the patent granted Ine September 27, 1859, entitled A new and improved stove, the object of which invention was to prevent the escape of smoke from the stove into the room when the door of the same was opened for replenishing the fIre, or for any purpose.

My present invention isl an improvement upon the arrangement described in the aforesaid patent for accomplishing the same object in a better and more efficient manner, at the same time placing the control of the valves under the entire management of the attendant without respect to the movement of the furnace-door, enabling the attendant to open the valves in starting the re, so as to obtain a greater draft when the furnacedoor is shut, or the valves can also be closed when the door is open, so as to diminish the draft, which is sometimes necessary in the event of strong winds to prevent the rapid consumption of the fuel and the stove from getting too hot.

. To enable those skilled in the art to understand my invention, I will proceed to describe its construction and operation.

A represents the shell of the furnace, which is shaped and constructed as described in my patent above mentioned, which has a furnacedoor B in front. From the front and rear ends of this shell A proceed up two pipes C C, which communicate with and sustain horizontal flues D, D', D,D, and E. The former ilues extend back the entire length of the shell A and are parallel with it, while the latter is a transverse iiue forming a commu-- clined pipe forming a communication between the upper flue D on the side of the stove to the lower flue D on the opposite side.

O is a short pipe communicating with the vertical pipe C and horizontal flue D', and H is a pipe communicating from the top of the vertical pipe O to the two uppertlues D D. The four longitudinal iluesDDDD are furnished with caps (not shown) on their front ends, which may be removed for cleaning the flues. This gives a description of the general arrangement of tlues through which the smoke and hot air is made to pass before they can escape up the chimney, and these may be multiplied to any desirable number, as may be found necessary in order to obtain greater radiating-surface and utilize the heat escaping from the furnace. This system of flues or drums is arranged in such a manner with respect to the vertical pipes O C that by furnishing these two pipes with a valve each, which is operated by connectingrods, as hereinafter described, I can obtain full control over the stove. These valves or dampers are therefore disposed and operated as follows:

J J are the valves pivoted in the vertical' pipes C C and operated so as to open and close by jointed arms and rods leading to the front of the stove. The valve J is `placed near the bottom of the vertical pipe C, while the valve J is placed in the vertical pipe O and intermediate between the branch pipes F and G. These two lvalves when closed have the effect to shut off a direct communication between the vertical pipes and the chimney, and when opened to create a very strong draft. When these valves are closed, the smoke is prevented from passing up the pipe C; but it is drawn to the rear of the shell Aand up the vertical pipe C to the branch pipe F. Then it is carried through drum D to the front of the stove and through pipe E to drum D thence to the rear of the stove again and up through the inclined pipe G to the drum D, and again back to the front of the stove,

and close the valves simultaneously by a slid? ing rod e, which passes through the front of the stove, so as to be handy for the operator:

This rod I intend to be operated by-hand and irrespective of the movement of the furnacedoor, for the purposes hereinabove mentioned.

`What I claim as my invention-,and desire to secu-reby- Letters Patent, .is- I In combination with a stove when the same is provided With two upright'pipes C C,com municating with and sustaining horizontal iiues arranged in relation to each other, substantially as herein described, the arrangement of the Valves J J 4operating Within the said pipes so as to open and close simultaneou'sly by means of connecting-rods or their equivalents, for the purposes herein set forth.
